App Store will not upgrade my iWork programs that I purchased on DVD (iWork retail V9.0.3) can't open new iWork files and polluting old files so they won't open.
Since I installed Mavericks, App Store shows all upgrades installed. However, old documents when first opened ask to be upgraded [click upgrade] then can't be reopened. Same for Keynotes, numbers, and pages. Uninstalled and reinstalled iWork from DVD. No upgrades avaialble in App store. Big "?" instead of Pages icon in dock and Keynotes and Numbers won't open at all saying the OS doesn't support. What can I do?
Mac Pro, Mac OS X (10.5.8), Final Cut Studio 2
